The drop-off was a family affair: Charlotte was not only joined by her parents but by her big brother, six year old Prince George.

Charlotte’s going into reception while Prince George is starting his third year at school - year two.

For the occasion, the Duchess Kate donned a belted, floral-print midi dress by US designer Michael Kors. It’s not the first time Kate’s worn the dress - it’s a past-season number that she first debuted during the rehearsal of Meghan Markle and Prince Harry’s wedding back in May 2018.
